To all whom it may concern:

Be it known that I, WILLIAM ROSE, a subject of the King of Great Britain, residing at Albion Yorks. Gainsborough, in the county of Lincoln, England, have invented new and useful Improvements in Apparatus for Securing the Folded Portions of Package lVrappers, of which the following is a specification.

This invention relates to apparatus whereby the folded portions of package wrappers, which are to be secured by adhesive material, are retained in contact with each other until the said adhesive material has become suf ficiently dry to give secure adherence of the folded portions, the said apparatus being of the kind in which the wrapped packages are carried between endless travelling belts the opposed inner runs of which are caused to exert resi'lent pressure upon the folded portions of the said articles until such time as adhesive material applied thereto has become sufficiently dry to secure the said folded portions. This invention has for its objectto provide an improved apparatus of the aforesaid kind whereby the folded portions of a succession of wrapped paclc ages, which may vary in size,'are more effectually retained in position by the inner runs of the travelling belts. The invention consists in the improved construction of apparatus hereinafter described wherein the inner runs of the said belts arecaused to resilently bear upon the folded portions of the articles by a series of rollers which are spaced apart behind and bear against the said inner runs, the said rollers of the'two series being arranged in a zig-zag, or staggered manner relatively to each other, so that packages of greater width than the distance between the opposed inner runs of the said belts will have its ends to which adhesive has been applied held down by the conjoint action of the belt on one side and a rolleron'the other side. This invention is not limited to application to wrapped packages, but I will, for the purposes of description presume that it is to be applied to securing wrappers enclosing tablets of chocolate, or'the like, for example, but it is to be understood that it can be applied in other analogous cases,'where it is desirable to hold portions of wrappers, or other articles, together until they adhere.

According to this invention a pair of properly tensioned endless travelling belts,

bands, or the like, (I will refer to them as belts) is provided each of the said. belts being carried by a pair of pulleys to which rotary motion is imparted to cause the belts to travel along at the same speed and a series of rollers, (which I will refer to as bearing rollers) bearing against the inner run of one of the said belts and another series of bearing rollers bearing against the inner run of the other belt. The axis of the rollers in each series are adjustably fixed and spaced apart a distance substantially greater than the depth of the ends of the said packages to which adhesive has been applied The series of bearing rollers appertaining to either one of the belts are arranged in a Zig-zag, or staggered, manner relatively to the series appertaining to the other of the belts, so that the bearing rollers of the series appertaining to either of the belts are in positions opposite the spaces between the bearing rollers appertaining to the series of the opposite belt.

Between the said belts a runner strip may be provided and supported so as to constitute the bottom of a channel or trough, of which the belts constitute the sides and this channel, or trough, may be provided with a cover if desired.

hen articles, to which, or to the wrappers of which, adhesive has been applied, are fed between the belts, so that the parts to which adhesive has been applied are presented to the belts, as the articles are carried along between the belts resilient pressure is exerted upon them by reason of the bearing rollers on either side acting against the band, on that side in opposition to the portions of the belt which are between the bearing rollers at the other side.

To adjust the distance apart of the belts and bearing rollers to suit the size of the articles being manipulated the series of the said bearing rollers at one side, or at both sides, are mounted in a support, or in supports, which can be adjusted and fixed in the adjusted position upon the framing, or table, of the apparatus.

In order that this invention and how i may be performed may be well understood I will describe, with reference to the accompanying drawings, a constructionin accordance therewith, promising that I do not limit myself to the precise details illustrated and hereinafter described. H

Figure 1 is a plan, FigureZ is a side elefor in size from the others.

vation, with a portion of one of the bellsremoved, to shew the rollers between the runs, and Figure 3 1s a transverse section on the line AB Figure 1.

Each of the endless belts (marked 1 and 23, secured to the base-plate, or table, 17, one

of which bearings (marked 10) is seen in Figure 2.

The pulleys 2 and 3 at the opposite end are rotatably mounted on spindles 11 and 11, respectively, which spindles are carried in slotted extensions (12 and 12 of the bracket 13' secured to the base-plate, or table, 17 by screws 24, so that the said spindles can be adjusted in the slotted members 12 and 12 to such positions that the desired tension can be iven to the belts.

Rotary motion is imparted to the main shaft 4, from an electric, or other suitable, motor, this motion being imparted to the pulleys, through the gearing described and thereby the belts 1, and 1 are caused to travel along at equal speeds.

The articles (such for instance as wrapped tablets of chocolate indicated at 15) are introducedby hand, or by any other suitable means, in succession, and in proximity to each other, between the opposed inner runs of the belts withthe parts to which adhesive has been applied next the belts which bear against those parts which in the instance mentioned are the folded portions of the wrappers and the belts carry the said articles along for delivery into any suitable receptacle, or to any required place.

A bottom runner strip 16 is formed on, or carried by, the base-plate, or table, 17, and in conjunction with the belts constitutes a channel along which the articles 15 are conveyed by the said belts.

The articles will be carried along by and ejected, or passed, from between the belts without the said articles being damaged, or

having undue pressure exerted upon them even if some of them should somewhat dif- The series of rollers 18 and 18, are re- .tatably carried on studs, (marked 19 and 19 respectively) secured to the bars 20 and 20, adjustably secured to the baseplate, or table, 17 by screws 21 passing through slots 22 and 22*, in ear-pieces projecting from the bars 20 and 20.

The rollers 18 and 18 are spaced apart behind, and so as to bear against, the back of the inner run of each of the beltsl and 1 so as to cause the saidinner runs to exercise pressure on the opposite ends, or sides,

articles is bearing against a portion of the? belt, against whieh a roller bears. will, at

its opposite end or side, be pressed upon by a partof the opposite belt, which is between two ad acent bearing rollers, and thus the folds, or portions, to which adhesive has been applied are held down by theconjoint action of the belts and therbearing rollers, the belts being tensioned so as to cause the said belts to exert the requisite resilient pressureon the ends, or sides, of the-articles" as they arecarried along between the belts. By these means a succession of articles, such, for instance, as wrapped packages, blocks, tablets, or cartons, containing mate rial (such for instance,v as'material in small particles, or in'a powdered, or. granular, condition; for instance,'tea, baking-powder,

or the like, or articles of a' fragile character, such as tablets, of chocolate, c1garettes, or

the like) can be carried along any desiredcure. the said folds, or portions, without damaging or breaking, the articles dealt with, even if their size should vary.

If desired, to" facilitate the drying of the said adhesive and further ensnre the adherence of the folds, or portions, to which it has been applied any suitable heating means may be employed; but as the heating means in itself does not form Vanypart' of this invention, itis not necessary for me to describe, orillustrate, it.

1. In apparatus for securing I the fold ed portions of package wrappers tojwhich adhesive has been applied, a pair of endless travelling belts so arrangedthat the packages to be dealt with can be introduced and carried along between the opposed. in-

ner runs of the said belts; in combination with a series of rollers bearing against the inner run of one of the saidbelts and anof the ends of the said packages to which adhesive has been applied and the said rollers in the two series being arranged in a staggered manner relatively to each other, so that packages of greater width than the distance between the opposed inner runs of the said belts will have its ends to which adhesive has been applied held down by the conjoint action of the belt on one side and a roller on the other side.

2. In apparatus according to claim 1, spindles on which said belt pulleys are mounted, slot-ted extensions on the apparatus adapted to receive the spindles of the belt pulleys at one end of the said apparatus and means for securing the said spindles in any desired position in the slots to adjust the tension of the said belts.

3. Apparatus for securing the folded portions of packages to which adhesive has been applied comprising a pair of endless travelling belts, pulleys carrying said belts, and spindles on which said pulleys are mounted, the said spindles at one end of the apparatus being adjustably carried in slotted extensions of the said apparatus and the spindles at the other end of the apparatus having rotary motion transmitted thereto so that the said endless belts are caused to travel at equal speeds; a bottom running strip constituting with the endless travelling belts a channel along which the articles are conveyed by the said belts; a series of bearing rollers rotatably secured to a bar and spaced apart behind and bearing against the inner run of one of the said endless belts and another series of bearing rollers rotatably mounted on studs secured to a bar and spaced apart behind and bearing against the inner run of the other endless belt, the bearing rollers of the said two series being arranged in a zig-zag or staggered manner relatively to each other, in combination with means whereby the bars carrying the respective series of bearing rollers can be adjustably secured to the apparatus so that the distance between the inner runs of the endless travelling belts can be adjusted.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM ROSE.
